The word 职位 is formed by combining two characters, each contributing a core meaning related to the concept of a job or role. The first character, 职 (zhí), carries the fundamental idea of "duty", "office", or "post". The second character, 位 (wèi), means "position", "place", or "status". When paired, they create a compound where the meanings reinforce and specify each other, with 位 acting to formalize and situate the concept of "duty" into a defined and official "position" within an organization, thus forming the complete notion of a professional post or job title.
